Go Green/Emerald Ash Borer

- Grangerford Heights is a classic example of what the emerald ash borer can do to a neighborhood full of ash trees.  This is the third time News 8 has visited the West Henrietta neighborhood, and the trees continue to look worse and worse.

Noreen Riordan of Summit Tree and Landscape said, "Definitely if not treated every ash tree will die."

The emerald ash borer was first noticed in New York in 2009.  It appeared in our area in 2010.  The green beetle tunnels through a tree's circulation, slowly killing it.  The DEC has put out a map showing the areas hardest hit.

"In this area, it is time to make a plan.  Either remove your ash tree, or get the treatment," Riordan said.

The treatment is an insecticide that can be injected into the trunk of the tree, but it must be done early, before the tree starts showing signs of damage. 

"Once you wait it is really too late.  You end up with a half alive tree, so you might as well inject it when it is healthy, and looking beautiful.  It's easy to see what a difference the treatment makes," Riordan said. 

Riordan added that many homeowners don't treat trees because of the cost, or they don't know they have ash trees.  The trees have opposite branching with a compound leaf and bark in a diamond shape pattern.  She is urging everyone to take action before it is too late.

"Right now, if you drive up and down the thruway both sides, you can see massive die back," she said.
